5、rica SANS 1618:2008 Edition 1.1 Table of changes Change No. Date Scope Amdt 1 2008 Amended to change the designation of SABS standards to SANS standards, to update the definition of “acceptable“, to update referenced standards, to change the requirement for a diluted solution, to include a new test
6、method for storage stability, and to move reference to legislation to the foreword. Foreword This South African standard was approved by National Committee StanSA SC 5110.07C, Timber preservation Timber preservatives, in accordance with procedures of Standards South Africa, in compliance with annex
7、3 of the WTO/TBT agreement. This document was published in April 2008. This document supersedes SABS 1618:1994 (first edition). In 6.2 reference is made to “relevant legislation”. In South Africa this means the Fertilizers, Farm Feeds, Agricultural Remedies and Stock Remedies Act, 1947 (Act No. 36 o
8、f 1947), as amended. Amdt 1 A vertical line in the margin shows where the text has been technically modified by amendment No. 1. Annexes A, B and C form an integral part of this standard.

11、deltamethrin in a hydrocarbon solvent that, when further diluted with an organic solvent, is intended for use as an interior insecticidal timber preservative. NOTE Deltamethrin does not afford any fungicidal timber protection. The possibility does, however, exist of obtaining broad-spectrum activity
12、, when deltamethrin is combined with a recognized and compatible fungicide. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this standard. All standards are subject to revision and, since any reference to a standard is
13、 deemed to be a reference to the latest edition of that standard, parties to agreements based on this standard are encouraged to take steps to ensure the use of the most recent editions of the standards indicated below.

Annex B (normative) Quality verification of insecti
36、cidal deltamethrin for interior use B.1 Quality verification When a purchaser requires ongoing verification of the quality of the timber preservative, it is suggested that, instead of concentrating solely on evaluation of the final product, he also direct his attention to the manufacturers quality s
37、ystem. In this connection it should be noted that SANS 9001 covers the provision of an integrated quality system. Amdt 1 B.2 Sampling and compliance with the standard B.2.1 Sampling B.2.1.1 General The following sampling procedure shall be applied in determining whether a lot, submitted for inspecti
38、on and testing, complies with the relevant requirements of this standard. The sample so drawn shall be deemed to represent the lot.

39、ard B.2.1.2.2 lot that quantity of timber preservative bearing the same batch identification, from one manufacturer, and submitted at any one time for inspection and testing B.2.2 Sample for inspection From the lot take at random a) five containers, if the lot is packed in containers of net volume n
40、ot exceeding 5 L; or b) three containers, if the lot is packed in containers of net volume exceeding 5 L. SANS 1618:2008 Edition 1.1 9 B.2.3 Sample for testing From the containers taken in accordance with B.2.2, draw, as follows, enough timber preservative to provide a composite sample of total volu
41、me at least 1 L: Take samples of approximately equal volume from the containers and immediately pour the samples into a clean, dry, airtight glass or plastics bottle clearly marked with the manufacturers name or trade mark, the batch identification and the date of sampling. Before drawing a sample,
42、thoroughly mix the contents of the relevant container. B.2.4 Compliance with the standard The lot shall be deemed to comply with the requirements of this standard if, after inspection of the containers and testing of the sample taken in accordance with B.2.3, no defective is found.
